[X][ISLANDS] Siege. Under constant, focused, withering artillery bombardment from naval and shore-based batteries, on soft, level ground, and with no real entrenching gear, the islands will be unable to hold out even if given an untouched supply line by air. Erode them over weeks of artillery bombardment, landing only once all activity has either ceased or been thoroughly suppressed.
[X][NEWS] Spread the word as far as it will go. Inform the world that you lived up to your promises. Ensure that everybody know that you beat Victoria. See if that shakes something loose from this embargo, and or perhaps motivates those foreign observers and spies to make recommendations at home.
And I can then get around to writing Part II of the CS propaganda, and possibly some propaganda from the general socialist side too (so as to not get into a rut).
@PoptartProdigy Do the Victorians have banners and the like that can be thrown at the feet of the triumphant Commonwealth leadership? (Like in those Soviet victory parade youtube videos I showed). And do they have some other major national symbols etc? Like eagles, statues of Victoria, flags, or copies of the anti-technology pledge?
